Due to the elastic element of the elastic pin coupling, the elastic element can produce greater elastic deformation and damping. Therefore, the elastic coupling can not only compensate for the relative displacement of the two shafts, but also cause buffering and vibration absorption.In the process of mechanical transmission, the load transmitted by the transmission shaft system often changes. The reasons for the load change are different, such as unstable motor speed, unstable load of working machine and centrifugal force caused by unbalanced rotating parts in the shaft system. Dynamic loads may cause changes in load.Load changes are often reflected in periodic loads, impact loads and irregularly changing loads, while elastic...

1. Dry coupling, without lubrication, elastic diaphragm couplings rely on metal diaphragms to transmit torque and absorb deformation caused by misalignment. There is no relative movement between parts and there is no friction and wear, so no lubrication is required. The development direction of oil-free process equipment.The gear coupling is a rigid movable coupling. It relies on the relative slippage between the tooth surfaces to compensate for the misalignment of the two shafts. Therefore, the gear coupling must be lubricated, and the lubrication condition determines the gear coupling. The key to good shaft work.Especially when running at high speed, it is more prominent, such as the separation and leakage of oil under the action of centrifugal force, and the...

The elastic coupling is a mechanical transmission device used to connect two shafts to rotate together to transmit torque and movement. It has a wide range of applications in various fields of the national economy.Since it is impossible to align the two connected shafts completely, the misalignment is caused by factors such as the manufacturing error of the unit, the installation error, the deformation after the load, and the temperature change.Therefore, the coupling is required not only to transmit torque and movement, but also to absorb the misalignment of the two shafts, and the additional impact on the unit should be as small as possible.The development and evolution of the coupling has always been carried out around this goal.There are many forms of couplings, depending on the function and principle...

1. Determine the transmission torque reasonably. Under normal circumstances, the transmission torque should be determined according to the actual transmission power and actual working speed of the unit. The diaphragm coupling is selected, so that the selected diaphragm coupling can not only meet the torque transmission requirements, but also the structure The lightest and the smallest additional force and bending moment to the unit.In order to pursue safety, some users increase the size of the coupling layer by layer when choosing the coupling. The couplings selected in this way are often too bulky and the use effect is not good.The coupling is subjected to the combined action of steady-state load CAL torque, axial misalignment medium ring mouth alternating load CAL alternating torque, angular and radial misalignment during operation.Coupling manufacturers in...

　Metal flexible diaphragm coupling (referred to as "diaphragm coupling") is a transmission device that uses metal flexible components to transmit torque without lubrication. It is widely used in ships, aviation, petrochemicals, and machinery. Manufacturing and other fields.The flexible element is a diaphragm group composed of a certain number of thin metal diaphragms from 0.2mm to 0.6mm.When working, the torque is input from the active flange, and the torque is transmitted to the metal diaphragm through the active torque transmission precision bolts arranged along the circumference, and then the diaphragm is transmitted to the driven flange output through the driven precision bolts.It produces bombs through a high-strength alloy diaphragm group...
